Wehrli Custom Fab 2004.5-2005 LLY Y-BRIDGE KIT
-3" Fabricated Y-Bridge
-3" Passenger Side Intercooler Pipe
-5/8" Heater Hose
The LLY 3" Y-Bridge Kit is an upgraded high flow intake kit for the 2004.5-2005 Duramax. The factory Y-bridge is a poorly designed two piece bridge that is prone to blowing apart under boost and creating poor drivability and excessive smoke. This is a one piece fabricated 3" bridge with a heavy duty machined bead roll on the inlet so the pipe cannot deform when the t-bolt clamp is tightened. A 3" high flow intercooler pipe compliments the y-bridge to offer a full 3" tract from intercooler to the engine. The 3" Y-Bridge (Bridge only, not the intercooler pipe) will work in conjunction with our S400 over stock Twin Turbo Kit if you decide to upgrade in the future.
